Description

Transformer neutral point duplex earthing isolator
Technical field：
The present invention relates to a kind of duplex earthing isolator, is grounded and isolates more particularly to a kind of transformer neutral point duplex Switch.
Background technology：
With expanding economy, social power consumption is increasing, and the quantity of transformer is also increasing, and neutral point is transformation An important part on device, still, neutral ground disconnecting link leaks in outdoor cruelly for a long time, does not operate for a long time, and service condition is poor, Contact oxidation causes contact resistance to increase, and fingertip spring pressure reduces, and contact resistance is had a very big dispersiveness, passes through during failure Zero-sequence current easy burn-out disconnecting switch, existing switch is that simply connected is set, in the presence of very big potential safety hazard when faulty.
The content of the invention：
The technical problems to be solved by the invention are：Overcome the deficiencies in the prior art, there is provided simple and practical, the Neng Gouyou of one kind The transformer neutral point duplex earthing isolator of the increase conductive cross-sectional area of effect.
The technical scheme is that：A kind of transformer neutral point duplex earthing isolator, including insulator, base, Connecting rod, wherein：The insulator is provided at both ends with base, and the base includes upper bed-plate and lower bottom base, the upper bed-plate On be provided with snap device, the connecting rod is connected with snap device and lower bottom base, and the connecting rod and lower bottom base pass through nut It is articulated and connected, the connecting rod is two, is arranged on insulator both sides, and parallel to each other.
Couple axle is provided between the connecting rod, the couple axle is articulated and connected with connecting rod by nut, the company Action bars is provided with moving axis, the action bars is articulated and connected with couple axle.
The base sheath is filled on the insulator, and the base is connected with binding post, is provided with the upside of the snap device Baffle plate.
The beneficial effects of the invention are as follows：
1st, the present invention is connected in parallel using two disconnecting switch, adds effective conductive cross-sectional area, and two disconnecting switch Folding is synchronous, prevent because one switch go wrong when, cause the damage of equipment.
2nd, baffle plate is provided with the upside of snap device of the present invention, baffle plate plays a part of rain-proof to snap device, prevents buckle Mechanism produces loose contact phenomenon because of the leaching brush by long-term rain, so as to influence the operation of equipment.
3rd, control stick of the invention is linked using handing-over, easy to use, moreover it is possible to while the folding of two disconnecting switch is controlled, Run using two switch in parallel, operating personnel is not influenceed the operation of equipment in the time of service switch.
Brief description of the drawings：
Fig. 1 is that transformer neutral point duplex is grounded isolated switch main view.
Fig. 2 is transformer neutral point duplex earthing isolator left view.
Embodiment：
Embodiment：Referring to Fig. 1 and Fig. 2, in figure, 1- insulators, 2- baffle plates, 3- snap devices, 4- upper bed-plates, 5- connections Bar, 6- lower bottom bases, 7- couple axles, 9- action bars, 10- nuts.
Transformer neutral point duplex earthing isolator：Including insulator 1, base, connecting rod 5, it is characterized in that：Insulator 1 is provided at both ends with base, and base includes upper bed-plate 4 and lower bottom base 6, is provided with snap device 3 on upper bed-plate 4, connecting rod 5 with Snap device 3 and lower bottom base 6 are connected, and connecting rod 5 is articulated and connected with lower bottom base 6 by nut 10, and connecting rod 5 is two, is set In the both sides of insulator 1, and it is parallel to each other.
Couple axle 7 is provided between connecting rod 5, couple axle 7 is articulated and connected with connecting rod 5 by nut 10, on couple axle 7 Action bars 9 is provided with, action bars 9 is articulated and connected with couple axle 7.
Base sheath is on insulator 1, and base is connected with binding post, and the upside of snap device 3 is provided with baffle plate 2.
In use, by action bars 9, switch is closed, when a switch goes wrong loose contact, electric current can lead to Cross another switch to flow through, do not influence the operation of equipment.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, it is all It is any simple modification, equivalent change and modification made according to the technical spirit of the present invention to above example, still falls within In the range of technical solution of the present invention.
